PowerEdge SC1420 won't boot

According to the following link you may have faulty hardware.

Look at Table 2-1 here.

IKtech... still no joy.  Don't have another processor.

So, I guess the flashing B indicator and power button can mean a bad PSU or MB...

the flashing power button can mean a variety of things.  Most common are memory and PSU.  So if you have ruled those out i would think it is the MB or the CPU.  Can you see any visable damage to the motherboard like swollen or bursting Capacitors or perhaps a melted chip.

You could try to reseat the processor.

MB looks good... this happened when the power company shut off power for 4 hours.

ahh and you replaced the cmos battery?


Having replaced the CMOS battery, verify the BIOS settings for what to do after a power failure (usual options are "off", "last state" and "on" -- You probably want "on").

Is there a jumper to clear cmos,  That might be worth a try

IKtech... well, tried the cmos jumper to no avail.

Replaced the cmos battery with a new one as well.

Losing the server isn't so bad except that it is an Exchange server and we'd want the old email...

I think that I have demonstarted that the MB is the issue...

Thanks.

I know you marked this question as answered but all the troubleshooting steps you took were a waste of time.

If you had followed the table I pointed you to you would have seen that:

The "A" diagnostic light being yellow with the system off and power applied is a normal state.

When you power the system on and receive the yellow light on the "B" diagnostic indicator it clearly states that you have a power issue. Whether it is in the PSU or MB is moot.

You are welcome.
